Intraspecific competition Intraspecific competition is in general stronger than interspecific competition. One reason is the similarity in resource requirements between the same species. Compare: interspecific competition; See also: symbiosis; competition

Niche differentiation Niche differentiation. The term niche differentiation (synonymous with niche segregation, niche separation and niche partitioning), as it applies to the field of ecology, refers to the process by which competing species use the environment differently in a way that helps them to coexist.

Competition (biology) Competition can occur between individuals of the same species, called intraspecific competition, or between different species, called interspecific competition. Studies show that intraspecific competition can regulate population dynamics (changes in population size over time).

- Pure competition is a market condition where the companies providing products offer the same features and price, making the difference between manufacturers minor, if not completely irrelevant. Once the products are part of pure competition, the sellers of those products often have similar sales.

Struggle for Life Intraspecific struggle for life is manifested in the competition between individuals of a given species when they encounter any enemies or harmful influences, in the competition for food and other vitally necessary factors such as water and light, and in the competition for the more effective protection of their life and offspring.

- The electron is a subatomic particle, symbol e− or β− , with a negative elementary electric charge.[8] Electrons belong to the first generation of the lepton particle family,[9] and are generally thought to be elementary particles because they have no known components or substructure.[1] The electron has a mass that is approximately 1/1836 that of ...

Evolution as a genetic function The biological species concept is the most widely accepted species concept. It defines species in terms of interbreeding. For instance, Ernst Mayr defined a species as follows:species are groups of interbreeding natural populations that are reproductively isolated from other such groups..The biological species concept explains why the members of a species resemble one another, i.e. form phenetic clusters, and differ from other species.When two organisms breed within a species, their genes pass into their combined offspring.he biological species concept explains why the members of a species resemble one another, i.e. form phenetic clusters, and differ from other species.

Rivalry (economics) In economics, a good is said to be rivalrous or rival if its consumption by one consumer prevents simultaneous consumption by other consumers, or if consumption by one party reduces utility/ability to use to another.

Species Species Concepts and the Definition of Species. 1) Biological species concept: Species are groups of actually or potentially interbreeding natural populations, which are reproductively isolated from other such groups (Mayr, 1940).) Competition species concept: Species are the most extensive units in the natural economy such that reproductive competition occurs among their parts (Ghiselin, 1974). 5) Ecological species concept: A species is a set of organisms exploiting (or adapted to) a single niche (Ridley 1993).

Intraspecific competition The way in which resources are partitioned by organisms also varies and can be split into scramble and contest competition. Scramble competition involves a relatively even distribution of resources among a population as all individuals exploit a common resource pool.

- Definition Of Competition. The Definition of Competition clause defines the scope of prescribed competition. The clause typically contains four elements: (a) restricted period; (b) restricted activities; (c) restricted business and (d) restricted territories. The component elements of the clause exhibit a high degree of conformity.

The Competitive Exclusion Principle Wiki: The competitive exclusion principle, sometimes referred to as Gause’s Law, is a proposition that states that two species competing for the same resource cannot coexist at constant population values, if other ecological factors remain constant.

Pure Competition: Definition, Characteristics & Examples Definition and Characteristics of Pure Competition. Pure competition is a term that describes a market that has a broad range of competitors who are selling the same products. It is often referred to as perfect competition. Here are some characteristics that define a pure competition. 1  In an ideal purely competitive market, the products being sold would be identical, which removes the option of one seller offering something different or better than another seller.

Perfect competition Perfect competition describes a market structure where competition is at its greatest possible level. Definition: Perfect competition describes a market structure where competition is at its greatest possible level. To make it more clear, a market which exhibits the following characteristics in its structure is said to show perfect competition: 1. Large number of buyers and sellers. 2.

ecological niche 1. the position occupied by an organism in relation to other organisms and to the environment. 2. a particular part of an ecological environment in which a particular plant or animal species prospers. It is the set of terms, in relation to food and water supply and relationship with predators and disease and with competitors, by which the organism achieves its full biological potential.

Competition Competition is, in general, a contest or rivalry between two or more entities, organisms, animals, individuals, economic groups or social groups, etc., for territory, a niche, for scarce resources, goods, for mates, for prestige, recognition, for awards, for group or social status, or for leadership and profit. It arises whenever at least two parties strive for a goal which cannot be shared, where one's gain is the other's loss. Competition occurs naturally between living organisms which co-exis

Biology in biology: Diversity. It has been suggested that sexual reproduction became the dominant type of reproduction among organisms because of its inherent advantage of variability, which is the mechanism that enables a species to adjust to changing conditions.

Competition and Cooperation Competition and cooperation are often juxtaposed, yet in the market they are two sides of the same activity. One of the oldest observations by economists is the way in which the division of labor and exchange enables an uncountable number of people to contribute to the production of any given product.

Predation A form of symbiotic relationship between two organisms of unlike species in which one of them acts as predator that captures and feeds on the other organism that serves as the prey. Supplement In ecology, predation is a mechanism of population control. Thus, when the number of predators is scarce the number of preys should rise. When this happens the predators would be able to reproduce more and possibly change their hunting habits. As the number of predators rises, the number of preys decline. This results in food scarcity for predators that can eventually lead to the death of many predators.

Mutualism (biology) Pollination is a classic example of mutualism. Mutualism is the way two organisms of different species exist in a relationship in which each individual benefits from the activity of the other. Similar interactions within a species are known as co-operation.
